Close-up view of salad greens (& purplish reds)

Before tossing  my baby kale and radicchio salad, I decided to take a peek with a foldscope:

Here are some shots taken under different lighting and magnification:

The stomata are prominent here.  As someone pointed out in my Instagram post, it is interesting that the cells containing the stomata have no color pigments. Any ideas?

    Dear @DOM,

    What a wonderfully appetizing set of images. Clearly the stomata cells have slightly dimmer pigments so they stand out. It surprises me tremendously, and I will ask more plant biology colleagues if this is true more generally of cells that support stomata.

    You beautifully connect science to food. Keep exploring.

    Fantastic. Would be great if you could digitally zoom in to one of the stomata. They stain really well. I have had good luck with methylene blue.

      Thanks for your wonderful suggestion! Will try it out.
